A CORPORATION OF NEW JERSEY.

CALGULATN To all whom it may concern:

Be it known that WILLIAM F. HAUS- sTnIN, a citizen of the United States, residing at Lyndhurst, in the county of Bergen and State of Newl Jersey, have invented certain new and useful Improvements in Calculating-B/lachines, of which the following is a specification.

This invention relates to calculating machines such as that which forms thefsubject matter of U. S. Patent to Alexander Rechnitzer, Number 809,075, granted January 8', 1906. In that machine the operations of addition, subtraction multiplication and division are performed, the multiplication consisting of repeated additions of the multiplier and the present invention relates to certain parts of the machinery for addition and subtraction. fin said machine there is a startinglever mounted 'on a rock shaft, the machine being started to perform the various operations by moving the starting lever to certain predetermined positions for the various Yoperations Which movements either rock or slide the rockshaft. Each step of an operation of addition or subtraction is performed duringione complete revolution ofthe mainshaft, and to start an operation of addition or subtraction, the starting lever is moved in 'euch a manner as to slightly rock the shaft upon which it is mounted. During any operation there is danger that the'starting lever may be accidentally moved out of its proper posi tion and the character of the operation changed and perhaps some of the parts. disarranged or broken besides Wasting the time occupied and compelling the resetting up of the mechanism and beginning the operation anew.

It is the special'object of this invention to rend'er suchI an accident impossible and the inventionv consists in providing such-.a Inachine with mechanism Which is o erative during the timefthe machine is per orming the various operations and Which during suoli operations Willsecurely lock the Astart-I ing lever in the position to which it has been brought to start the machine, such mechanism at the end of each complete revolution 0f the main shaft, being automatically released permitting the starting lever to return to its Specicaton of Lettera Patent. Application filed November 8, 190e. Seri No. Zlill..

Eatented Dee. E.,

ing the present invention, parts being broken away, parts shown in dotted lines, and the starting lever in section, 2 is a partial front eievationvvith the front'of the casing removed, Fig. 3 is a partial sectional view on a piane cutting transversely partially through the bottom of lthe casing, showing some of the mechanism in end elevation, 'just after a complet-e revolution of the main shaft, Fig. e is a similar view with the parts in position at the end of a complete revolution of the main shaft, Fig. 5 is a partial bottom plan view, Fig. 6 is' a plan View of part of the machine with the top plates renier/ed, Figs. 7 and 8 are detail plan views of some of the parte shown in Fig'. 6, in dilerent positions, and Fig. 9 is-an enlarged sectional detail on line 9-9 of Figr 6.

- In the original machine there is a shaft 6 journaled in bearings 7 on the ba of the machine, upon whichv shaft is secured the starting lever 8 which normally projects upward through a longitudinal slot 9 in the top plate l0 of the stationary part of the machine. From this slot extend lateral branch slots ll and l2 into which the starting lever 8 is moved to start the machine to perform the operation of addition or subtraction, said lever being movable also to either end, 13 or let of the slot 9 to start the machine to perform the operation of multiplication or division.v

The main shaft of the machine is shown at 15 and as each complete revolution of the shaft completes an addition or subtraction operation, the starting lever must be maintained in position until an operation is Colnpleted or until one revolution ef the main shaft is made.

The special mechanism of this invention comprises "devices for locking vthe starting lever until .the end of the revolution of the main shaft required to complete an operanormally held in Contact With that partof the plate 16 which projects above the shaft- 6 by a spring 22. rThis also normally presses the other or hook end 21 of the pawl into contact with the periphery of the cam 23 secured on the main shaft 15 and which is provided with a tooth 2l; the cam being adjusted or timed on the main shaft so as to cause the tooth 2l to engage and press down the hook end 21 of the paivl 19 at the end of each revolution of the main shaft at the completion of each operation of the machine. This operates the paivl to raise and release its front end 2O from engagement with the broad pavvl 1.6, permitting said pavvl 16, under the action of the spring 17, to roclr the shaft 6 and move the starting lever out of the branch slot 11 or 12, into which it has been moved to start the machine. rlhe starting lever thus assumes its inoperative position. in the slot 9 as shown in Figs. 1 and holding the end 2O of the pawl 19 raised until the starting lever is again moved into one of the branch slots 11 or 12 to again start the machine. As soon as the starting lever is again moved to start the machine, the end 20 of the paWl-19, under the inliuence of the 22, drops down behind the upper end the broad pawl 16, thus preventing the rocking of the shaft 6, and locking the starting lever in position until again released in the manner before describec.

To the right of Fig. 1 is shovvn suiiicient of the calculating mechanism of the Bechnitzer calculating machine to identify the connection of the mechanism of the present invention therewith, the slots and slides for indicating the amounts to be added or subtracted being indicated at 25,26, 27 and 28, and the numeral Wheels for indicating the results, at 29. y

r)The main shaft 15 is connected by gearing 30 With a shaft 31 which in turn is connected, by bevel gearing 32, with the shafts (not shown) of the drums which latter carry teeth 34 of graduated length. As slidable gears 35 are adjusted (by slides 26) on shafts these shafts are rotated a distance determined by the positions of the slides and as they are connected, by gearing 37 with the numeral Wheels 29, said numeral Wheels are correspondingly rotated and the various calculating operations performed in the manner fully explained in the specification of the Reclinitzer patent, hereinbefore referred to.

The main shaft is driven by a motor, as at 39 in Fig. 6 and is connected, disconnected and reversed by mechanism illustrated in said ligure and Figs. 7, 8 and 9, which is also illustrated and described in my Patent #888,403, granted March 31, 1908 and forms no part of the present invention but is lshown and described herein merely to more clearly illustrate the .connection of the mechanism of the subject matter hereof with the driving mechanism ofjthemachine.

The motor shaft 39 carries a Worm meshing With Worm-Wheel 40 on shaft ll1, which latter, by the clutch mechanism 42, actuates a shaft 43 connected by gearing (not shown) with the shaftA and also with a shaft ill, the latter being .connected by gearing Ll5 with a shaft 16 carrying a pinion 47 which meshes with `a rack (not shown), on the sliding carriage.

The carriage, at the end of its stroke, strikes a lever 4S and thus, through the medium of a link 19 'and lever 50, automatically reverses the movement of the mechanism, thus returning the carriage, all as fully described -in said co-pending application.

The starting lever rock shaft 6 carries a hub 51 from which ects a pin 52 into a slot 53 in a slidable plate 54 so that When thestarting lever is moved into or out of branch slots 11 or l2 the shaft 6 is rocked, thus sliding plate 5l which operates an elbow lever 55 connected by a bar or link 56 with the clutch mechanism, thus actuating` the latter to start or stop the machine.
